Overview
The MCC 1N5819-AP is a Schottky barrier rectifier housed in the DO-41 axial package. It features a maximum repetitive reverse voltage of 40 V and an average forward current rating of 1 A. The device exhibits a low forward voltage drop ranging from 0.45 V to 0.60 V at 1 A, with a peak non-repetitive surge current capability of 30 A. Operating junction temperatures span from -55°C to 125°C, while storage temperatures extend up to 150°C. The suffix '-AP' designates RoHS compliant packaging in an ammo box format.
Feature Summary
- Guard ring protection structure for enhanced reliability
- Low power loss characteristics suitable for high efficiency applications
- Epoxy material meets UL 94 V-0 flammability rating
Applications
- Switch mode power supplies
- High frequency DC to DC converters
- Low voltage high frequency inverters
- Free wheeling diodes
- Polarity protection circuits
- Small battery chargers
Procurement Notes
Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors. Counterfeit parts are prevalent; unauthorized sources lack traceability and warranty coverage. Confirm the '-AP' suffix indicates the specific ammo box packing configuration required for your assembly process. Ensure compliance with RoHS standards as designated by the 'P' suffix.
Selection Notes
Select this component for applications requiring low forward voltage drop and fast switching speeds. The DO-41 through-hole package facilitates standard PCB mounting. Consider thermal resistance limits when designing heat dissipation strategies. Verify that the 40 V reverse voltage rating exceeds the circuit's peak operating voltage to prevent breakdown.
Part Context
This part belongs to the 1N5817 through 1N5819 series of axial power Schottky rectifiers manufactured by Micro Commercial Components. The series shares identical physical dimensions and electrical structures, differing primarily in their peak repetitive reverse voltage ratings. The 1N5819 variant specifically targets circuits requiring up to 40 V blocking capability.
Replacement Considerations
Cross-reference with other manufacturers offering 1N5819 equivalents in the DO-41 package. Verify that substitute components meet the same 1 A forward current and 40 V reverse voltage specifications. Ensure thermal resistance and forward voltage characteristics align with original design requirements.
